I am soon to go snowboaridng for the season in canada . I am hoping to make a snowboarding movie whilst i am over there. Im looking for a camera with a smooth non grainy image that looks as profesional as possible and tht also has a fast frame rate. (For slowed down failed backflip atempts)

Im also on a bundget and so far the only two that have caught my eye are:

Sanyo Xacti HD2 High Definition Camcorder
and the
Aiptek Pocket DV Z300HD

are these completly wrong for what i want them for? (ive been looking at high def as i assumed this was the only way to get profesional looking pictures.)

I know nothing about camcorders so any help would be appreciated.

Thanks!
